2. How and why it damages the light
of the screens?
the electronic devices we use in our day to day, has become something essential.
but do we know about the blue light they give off and the drawbacks they may
have on the eyes?

3. What is the blue light?
the light is blue is the one that makes the screens
of our devices appear white, without this the
screens would look yellowish

5. the time of exposure depends on each person, whether it is working on the
computer and other factors, the longer we are in front of a screen more damage is
going to cause.
34% go from 4 to 6 hours in front of a device, 14% from 10 to 12 hours and 10%
more than 12 hours. In addition, 2 out of 3 people between 30 and 60 years of age
have the computer visual syndrome that results in:
*Headaches.
*Insomnia.
*Visual fatigue.
*Visual stress.
*Red and irritated eyes

7. 1.
glasses against blue light
the function of these
glasses is that when
using the screen is not
going to look white as is
usual, what you will do is
to be able to see in a
yellow color and this
makes us protect from
the blue light

8. 2.
software
there are applications or
programs that make the
screens of our devices
have a yellow color to
simply contrast the blue
light is not the best
alternative but can help
us

9. some tips that can serve us as:
• it is advisable to have a good distance between us and
the screen
• rest your eyesight for a certain period of time
• you have to keep the brightness of the screen
according to the ambient light that we have, that is
not much brightness or that the brightness is too
little because we force the view more
